SSL Problems

Problem started yesterday. I was working on custom packages for cPGS using console (Putty) when my connection just dropped.

Now I can't login at all to my dedi's Main cPanel or through client including sftp & remote logins! My game servers are up and running with cPGS though I have no connections to MySql being excepted. Has anyone got any idea's what has happened?

Error in Firefox:
Secure Connection Failed
An error occurred during a connection to XXX.XXX.XXX:XXXX
SSL received a record with an incorrect Message Authentication Code.
(Error code: ssl_error_bad_mac_read)
